Polymeric shock absorbing element for a vehicle and longitudinal side member

Polymeric shock absorbing element (10) for a vehicle comprising:

• a honeycomb structure (20) having a plurality of channels (30) realized by moulding into a single piece with a polymeric material, each channel (30) is preferably equipped with a hexagonal section;
• said honeycomb structure (20) has an lateral external surface (22) which extends from a first open frontal end (12) to a second open rear end (14);
• said plurality of channels (30) extends internally to said shock absorbing element (10) starting from said first open frontal end (12) to said second open rear end (14);
• each channel (30) of said plurality of channels (30) being internally tapered towards said second open rear end (14) and having an inner rake angle included between 0° and 1.5° measured with respect to a longitudinal extension axis (98) of each channel (30);
• said shock absorbing element (10) being insertable and fixable within an internal lateral cavity (85) of a chassis of said vehicle, where said internal lateral cavity (85) is defined by at least two metallic plates (81) and (82) comprising a first metallic plate (81) and by a second metallic plate (82) which are welded together or which are made integral with each other for forming a longitudinal side member (80) of said vehicle,
• wherein said lateral external surface (22) comprises at least one planar face (24) positioned on one side of said polymeric shock absorbing element (10) and additionally said polymeric shock absorbing element (10) comprises at least one metallic fixing element (50) which includes a central portion (51) having a first central wall (53) which is made integral to a corresponding planar face (24) of said lateral external surface (22), said at least one metallic fixing element (50) additionally comprising a plurality of fastners (56) lateral to said honeycomb structure and which are respectively welded or made integral with a plurality of corresponding inner walls of said first metallic plate (81) and/or of said second metallic plate (82),
• wherein said lateral external surface (22) of said honeycomb structure (20) comprises two planar faces (24) which are positioned on two opposite sides of said polymeric shock absorbing element (10) and said at least one polymeric shock absorbing element (10) additionally comprises a first metallic fixing element (50) and a second metallic fixing element (50b), which are positioned on opposite sides with respect to said honeycomb structure (20), and which are oriented along a longitudinal direction (95) of extension of said internal lateral cavity (85), and
• wherein said first central wall (53) of said first central portion (51) of said second metallic fixing element (50b) has a lower height with respect to said first central wall (53) of said first central portion (51) of said second metallic fixing element (50).
